Anleitung Zusammenfassung
MUFFLER SPARK ARRESTOR IMPORTANT Carbon deposits in muffler will cause a drop in engine output and overheating. Spark arrestor screen must be checked periodically. 1. Remove muffler cover screws and remove muffler cover. 2. Remove spark arrestor screen cover, gaskets, and screen from muffler body. 3. Clean carbon deposits from muffler components NOTE When cleaning carbon deposit, be careful not to damage the catalytic element inside muffler. 4. Replace screen if it is cracked, plugged, or has holes burned through. 5. Assemble components in reverse order. Cylinder Exhaust Port IMPORTANT The cylinder exhaust port must be inspected and cleaned of excess carbon every 3 months or 90 hours of operation in order to maintain this engine within the emissions durability period. ECHO strongly recommends that you return your unit to your ECHO dealer for this important maintenance service. 19 CARBURETOR ADJUSTMENT Engine Break-In New engines must be operated a minimum duration of two tanks of fuel break-in before carburetor adjustments can be made. During the break-in period your engine performance will increase and exhaust emissions will stabilize. Idle speed can be adjusted as required. BEFORE MAKING ADJUSTMENTS: • The correct spark plug must be clean and properly gapped. • The air filter element must be clean and properly installed. • The muffler spark arrestor screen and exhaust port must be clear of carbon. • The standard bar and chain combination (see page 4) must be installed to the power head, and properly tensioned. LOW ALTITUDE ADJUSTMENT Engines that have been adjusted to operate at high altitudes must be readjusted to operate properly at altitudes below 2000 feet. B A 1. Start engine and run for several minutes to reach operating temperature. 2. Stop engine. Remove grommet cover (A) over “H” and “L” limiter needles. 3. Start engine and turn the high-speed needle rich (CCW) until the engine runs between 12,000 and 12,500 RPM. Then turn the low-speed needle rich (CCW) until the engine does not hesitate when accelerated. DO NOT REMOVE LIMITER CAPS! 4. Idle Speed Adjustment. • Start engine and turn “idle” speed adjustment screw (B) CW until the saw chain begins to move, then turn the screw CCW until saw chain stops moving. Turn screw CCW an additional 1/4 turn. 5. Accelerate to full throttle for 2-3 seconds to clear excess fuel from engine then return to idle. Accelerate to full throttle to check for smooth transition from idle to full throttle. If engine stops or stalls after full warm up return the unit to your authorized ECHO dealer for adjustment. 6. Install grommet cover (A) over “H” and “L” limiter needles. HIGH ALTITUDE ADJUSTMENT High altitude adjustment may be required for proper operation of this engine above 2000 feet. 1. Start engine and run for several minutes to reach operating temperature. 2. Stop engine. Remove grommet cover (A) over “H” and “L” limiter needles. 3. Start engine and turn the HI speed needle lean (CW) until the engine runs between 12,000 and 12,500 RPM. Then turn the LO speed needle lean (CW) until the engine does not hesitate when accelerated. DO NOT REMOVE LIMITER CAPS! 4. Idle Speed Adjustment. • Start engine and turn “idle” speed adjustment screw (B) CW until the saw chain begins to move, then turn the screw CCW until saw chain stops moving. Turn screw CCW an additional 1/4 turn. 5. Accelerate to full throttle for 2-3 seconds to clear excess fuel from engine then return to idle. Accelerate to full throttle to check for smooth transition from idle to full throttle. If engine stops or stalls after full warm up return the unit to your authorized ECHO dealer for adjustment. 6. Install grommet cover (A) over “H” and “L” limiter needles. 20 CHAIN AND GUIDE BAR COMBINATIONS The following combinations may be used on CS-305 and CS-306.

Only use saw chain designated as, “LOW-KICKBACK,” that meets the ANSI B175.1-2000 Standard, and the Echo guide bar specified. IMPORTANT Chain and guide bar gauge size must be identical. Use Bar/Chain combinations shown in table above. IMPORTANT If your kick guard is damaged or lost, contact your Echo dealer for a replacement. For the name of the Echo dealer nearest you, Call: 1-800-432-ECHO (3246) or on the web at com. Refer to your Chain Saw Safety Manual for kick guard application information. 21 SETTING THE SAW CHAIN For setting saw chains, round file 4.5 mm (11/64”) and flat file are used. • To keep correct position and correct angle, use the file holder. ...
